Hello,

Here are the sip traces of two legs
leg1 UAC -> proxy -> media
leg2 media -> proxy -> provider
from leg1,
when freeswitch(media) is sending back 480 temporarily unavailable after 183 session progress, UAC is sending ack and bye, now in return freeswitch is sending '481 Call Does Not Exist'

my question is why? why freeswitch is sending 481 in return of ack and bye?

here,
11.23.16.12 is UAC
11.23.16.13 is Opensips(Proxy)
11.23.16.16 is Freeswitch(Media)

Thanks,
Devang Nathwani
